Overview

Miami County is located in Ohio with a population of approximately 110,000. The Miami County Probate Court handles all probate and estate matters for decedents who were domiciled in the county at the time of death.

Ohio probate is governed by Title 21 of the Ohio Revised Code. The process begins with filing a Application to Probate Will (Form 2.0) or Application for Authority to Administer Estate (Form 4.0) to admit the will and appoint a personal representative. The court then issues Letters of Authority for testate estates or Letters of Administration for intestate estates.

Ohio offers simplified procedures for smaller estates:

* Summary Release from Administration: Available if the estate is worth less than $5,000, or up to $45,000 if the surviving spouse is the sole heir and pays funeral expenses.

* Release from Administration: Available if the estate is valued at $35,000 or less, or up to $100,000 if the surviving spouse is the sole heir.

Ohio sets statutory executor fees based on the value of the estate: 4% of the first $100,000, 3% of the next $300,000, and 2% of assets above $400,000.

Filing Process

Step 1: Determine If Probate Is Necessary

Before filing, assess whether formal probate is required:

  • Summary Release from Administration: If the estate is valued at $5,000 or less (or $45,000 if the spouse is the sole heir).
  • Release from Administration: If the estate is valued at $35,000 or less (or $100,000 if the spouse is the sole heir).
  • Trust administration: Assets held in a living trust generally do not require probate.

Step 2: File the Petition

If formal probate is needed, file an Application for Authority to Administer Estate (Form 4.0) with the Miami County Probate Court. Include:

  • Application to Probate Will (Form 2.0) if there is a will
  • Original will and codicils (if any)
  • Certified death certificate
  • Filing fee deposit (typically ~$250 for full administration)
  • Surviving Spouse, Children, Next of Kin, Legatees and Devisees (Form 1.0)

The court accepts filings in person or by mail.

Step 3: Provide Notice

After filing, you must:

  • Mail notice of the hearing to all heirs, beneficiaries, and interested parties at least 7 days before the hearing (or obtain waivers).
  • Publish notice in a newspaper of general circulation in Miami County (e.g., Miami Valley Today) if addresses are unknown or as required by local rule.

Step 4: Attend the Hearing

The court will schedule a hearing on the petition, typically 2 to 4 weeks after filing. At the hearing, the judge reviews the petition and, if approved, issues Letters of Authority.

Step 5: Administer the Estate

After receiving Letters, the personal representative must:

  • Notify creditors — creditors have 6 months from the date of death to file claims.
  • Inventory and appraise all estate assets within 3 months of appointment.
  • Pay valid creditor claims.
  • File federal and state tax returns as needed.
  • Distribute assets to beneficiaries.
  • File a final accounting (Fiduciary's Account) and petition for discharge.

Local Requirements

  • Filing Deposits: The court requires a deposit for costs at the time of filing.
  • Publication: Notice must be published in a newspaper of general circulation in Miami County, such as Miami Valley Today.
  • Counsel: While not strictly required, the court strongly recommends retaining counsel due to the complexity of probate law.
